Question

How do I load variables from a .env file in Wolfram Language?

Storing secrets and configuration in a .env file is a widely adopted industry convention (popularised by the twelve-factor app methodology). Most languages have first-class support for it. In Python, this is commonly done like so:

from dotenv import load_dotenv
import os
load_dotenv()
api_key = os.getenv("MY_API_KEY")

Given a standard .env file like:

# example .env file
STRIPE_API_KEY=scr_12345
TWILIO_API_KEY=abcd1234

what is a clean and idiomatic way to load these variables from a .env file in Wolfram Langauge?

This functionality could be a nice addition to the function repository.
